Answer:
2 Kg and 2.5Kg.
Step-by-step explanation:
Total number of parts = 4 + 5 = 9.
So the required quantities are 4*4.5 / 9 and 5*4.5/9
= 2 and 2.5.
Answer:
2 : 2.5
Step-by-step explanation:
4 : 5 ----> 4x, 5x
4x + 5x = 4.5
9x = 4.5
x = 4.5 / 9
x = 0.5
4x
= 4 x 0.5
= 2
5x
= 5 x 0.5
= 2.5
4 : 5
= 4x : 5x
= 2 : 2.5
